DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] To solve the technical problem of how to apply the lifting fixture to railway wheels with different wheel diameters, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0021] An adjustable railway wheel hoisting fixture comprises a suspension rod 1, a clamping claw 2 and a wheel body 3. A suspension ring 11 is installed in the middle of the suspension rod 1. The interior of the suspension rod 1 is hollow and a bidirectional screw 13 is movably installed. One end of the bidirectional screw 13 is fixedly connected to a motor 14.

[0022] There are two clamping jaws 2 and they are symmetrically arranged about the lifting ring 11. The clamping jaw 2 includes a rod sleeve 21, which is slidably connected to the lifting rod 1. A threaded sleeve 211 is connected to the rod sleeve 21 through a connecting block 212. The threaded sleeve 211 is threadedly connected to the bidirectional screw 13. The rod sleeve 21 is connected to a claw head 23 through a clamping rod 22. A clamping groove 231 is provided at the clamping end of the claw head 23, and the clamping groove 231 is snap-connected to the wheel body 3.

[0023] Among them, a slide groove 12 is opened on the surface of the suspension rod 1, and the connecting block 212 is slidably connected to the slide groove 12. The slide groove 12 is provided to provide a precise sliding path for the connecting block 212 to ensure that the clamping jaw 2 makes a linear motion during the adjustment process, thereby ensuring the alignment and clamping accuracy of the clamping jaw 2 and the wheel body 3.

[0024] Specifically, start the motor 14, and the motor 14 drives the bidirectional screw 13 to rotate. Since the threaded sleeve 211 is threadedly connected to the bidirectional screw 13, and the threaded sleeve 211 is slidably connected to the slide groove 12 through the connecting block 212, the threaded sleeve 211 can drive the rod sleeve 21 to slide stably along the suspension rod 1, and the rod sleeve 21 then drives the claw head 23 to move through the clamping rod 22, so that the left and right claw heads 23 can move toward or away from each other, thereby adjusting the width of the clamping groove 231, which is suitable for clamping wheel bodies 3 with different wheel diameters.

[0025] To solve the technical problem of how to adapt the lifting fixture to railway wheels of different wheel widths, please refer to Figure 3 , this embodiment provides the following technical solutions:

[0026] A pressing plate 232 is provided in the clamping groove 231 for lifting and lowering, and a cylinder 233 is installed on the top of the claw head 23. The cylinder 233 is connected to the pressing plate 232 through a piston rod, and the pressing plate 232 is slidably connected to the claw head 23 through a sliding rod 234.

[0027] Among them, the sliding rod 234 is set to provide vertical guidance for the pressure plate 232, ensuring the linear movement of the pressure plate 232 during the lifting process, thereby ensuring uniform compression of the rim of the wheel body 3, avoiding deformation or damage of the wheel body 3 due to uneven compression, and also helping to reduce the friction between the pressure plate 232 and the claw head 23.

[0028] Specifically, after the claw head 23 clamps the wheel body 3, the cylinder 233 is started, and the cylinder 233 drives the pressure plate 232 to move downward through the piston rod until the pressure plate 232 is tightly pressed on the upper surface of the rim of the wheel body 3, thereby clamping the wheel body 3. This is suitable for clamping wheel bodies 3 of different wheel widths.

[0029] Working principle: When using the adjustable railway wheel lifting clamp, the motor 14 is started first, and the motor 14 drives the bidirectional screw 13 to rotate. Since the threaded sleeve 211 is threadedly connected to the bidirectional screw 13, the threaded sleeve 211 is slidably connected to the slide groove 12 through the connecting block 212, so that the threaded sleeve 211 can drive the rod sleeve 21 to slide along the suspension rod 1, and the rod sleeve 21 drives the claw head 23 to move through the clamping rod 22, so that the left and right claw heads 23 move toward or away from each other to adapt to the different wheel diameters of the wheel body 3. After the claw head 23 initially clamps the wheel body 3, the cylinder 233 is started, and the cylinder 233 drives the pressure plate 232 to move downward through the piston rod. The pressure plate 232 moves vertically under the guidance of the slide rod 234 until the pressure plate 232 is tightly pressed on the upper surface of the rim of the wheel body 3 to adapt to the different wheel widths of the wheel body 3.
